To all whont it may concern:

Be it known that 1, WILLIA R. MCKEEN, Jr., a citizen of the'United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Heating and Ventilating Systems; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to heating and ventilating systems, and is particularly directed ployed-to' cool the operative parts thereof may beutilized for heating 13,11 to be conducted into the interior of a car.

Other objects will be in part obvious and in art pointed outhereinafter. 4 he invention accordingly consists in the features of construction; combinations of elements, and arrangement of parts, which will be exemplified in the apparatus hereinafter described, and the scope of the application of which will be indicated in the following claims;

n the accompanying drawings, wherein is illustrated one of the various possible embodiments of my invention, Figure 1 is a view in side elevation of the framework of a motor-propelled car, showing the same embodied therein. Fig. 2 is a top plan view of the same, showing the floor-framework of the car, some of the parts being broken away.

' Similar reference characters refer to similar parts throughout both figures of the drawin s.

lreliminary to a description of the specific features of my invention and as conducive to a clearer understanding of certain of the objects thereof, it may here be noted that in IIZOtOT- ropelled cars wherein engines of the interna -combustion type are employed to furnish the motive power therefor it is necessary to provide means to cool certain operative parts of the engine. I have therefore of the ordinary pilot of a locomotive.

found it desirable to provide a heating and ventilating system such that the heat enerated by the engine is not dissi ated, but is utilized to accomplish hi hly eneficial results in heating and venti atirrg the car, the

system being so constructed and arranged as 1 to furnish at will either hot or cold air to the interior of the car and to regulate the quantities thereof so furnished.

In order to secure these among other results, I employ a structure involving the features disclosed in the accompanying drawings, in which 1 indicates the framework of the car, which, as far as the present invention is concerned, may be. of any preferred ty e.

It may here be noted that the type of car herein illustrated embraces novel features of construction, to which features no claim is made in this case, the same being shown, described, and claimed in my copending appli- Suitably, mounted in the framework or upon one of the trucks carrying the same are any well-known type of internal-explosion engines. 2 2, which engines are provided with the usual water-jackets for maintaining the engines atthe required low temperature. All of said water-jacketsare connected by a suitsaid water-jackets, and all of the water-jackets are connected attheir lower ends by a similar pipe 4. A pi e 5 communicates with the pipe 3 and exten s forwardly to and communicates with a tubular pilot 6. i

The pilot 6 is made upof a bent tube producing a fender adapted to serve the purpose The pilot-tube sections are arranged substantially vertically and are given, preferably, a slight inclination, and at the end of the continuous tube constituting the pilot said tube communicates by a pipe 7 with transversely-.

positioned coils 8 8, and the last of said coils communicates with the 'pipe 9, leading to the pipe 4. Thus in operation the water in the cation, Serial No.260,524;,fiied May 15, 1905.

jackets of the engines 2, rising undert'he action of the heat, passes out through the pipe 3, pipe 5, and pilot 6 to the coils 8, and thence.

- pump (notherein shown) may be interposed in the system for accelerating the circulation, if desired, and the ordinary radiate i ing-flanges, such as are seen at 10, may be arranged on the several tubes of the circulating system for aiding in the dissipation of the car provided with the system above described moving forward subjects such cooling system to the fresh air through which the car is passing, and therefore effects a perfect cooling of the system. The air passing throu h the pilot and the coils in the rear of the pi ot absorbs the heat from the system, and therefore itself becomes heated, and in order to heat the interior of the carwhen desired I propose to provide means for directing such eated air into the interior of the car or for disposing of such heated air outside the car when it is not desired to heat the car. pilotserves as a preliminary heater to temper the air, which is thereupon deflected by the baffle-plates 13 and the current thereof concentrated and thrown into the closely-disposed members of the coil 8. The latter serves to bring the tempered air to a yet higher degree of temperature and transmit the same toward the car, as hereinafter described. To attain this result, a closed base 11 is provided for the pilot 6, and a cover 12 is formed therefor, and each of the tubes of the pilot at each side of the car is provided with a shield or bathe-plate 13, directing the air inwardly into contact with a hood 14, arranged transversely of the car and extending for the width thereof, said hood being provided with a divide or vertical web 15, arranged centrally of the car, and the hood is positioned with its walls inclined rearwardly from such divide, so that approximately onehalf of the heated air passing through the pilot and coils into the hood is directed to each side of the car, and at each side of the car is arran ed an air-conduit 16,-each of said conduits being provided with a discharge 17, normally closed by valve 18, each valve 18 being provided with a stem 19', connected with the pintle of the valve and designed to be operated for swingin ,the valve from the position indicated in full ines in Fig. 1 to the position indicated in dotted lines therein or for swinging the valve from the position indicated in dotted lines to the position indicated in full lines, it being observed that when the valve is in the position indicated in full lines the heated air will be directed throughout the length of the conduit 16, while when the valveis in the,

position indicated in dotted lines the heated air will be discharged out discharge opening17.

ei'aeee ranged in the flume and adapted to control the amount of air admitted through the flume. The cool-air flume 20 and the heated-air conduit 16 unite within the carat the point 23 and extend rearwardly in the form of an enlarged ductat the side of the car, suitable registers being arranged, as at 24 2 1, along the length of each of said enlarged ducts.

Havmgfldescribed my invention, together with its method of use, it will accordingly be seen that I have provided a ventilating sys tem characterized by increased simplicity and efficiency. The heated coils perform the double function of furnishing a cooling means for the propelling mechanism of the car and heating the air employed in the ventilation thereof. The

provision of the conduits, one of which lea s from the coils and the other leading from without the roof of x the structure, and the regulating-valves insures a proper mixture of hot and cold air and provides for the conduction of either into the interior of the car in the desired amount.

As many changes could be made in the above construction and many apparently widely difierent embodiments of my invention could be made without departing from the scope thereof, I intend that all matter contained in the above descriptionor shown in the accompanying drawings shall be interpreted-as illustrative and not in a limiting sense. I desire it also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention, herein described and all statements of the sco e of the invention, which as a matter of anguage might be said to fall therebetween.
